Memory IC Procurement Notes

Verify component authenticity through authorized Renesas Electronics Corporation channels due to discontinued status. Confirm RoHS compliance requirements as the specific part may not meet current environmental standards. Validate package integrity upon receipt to ensure suitability for automated surface-mount assembly processes.

Memory IC Selection Notes

Select this component when a 256K x 18 organization is required with 133 MHz synchronous performance. Ensure design compatibility with 3.3V logic levels and 100-pin TQFP footprint constraints. Consider thermal management capabilities within the specified commercial temperature range during PCB layout.

Memory IC Part Context

This part belongs to the IDT 71V3558 family of synchronous ZBT SRAMs. It shares architectural similarities with other variants in the series but differs in speed grade and packaging. The XS suffix indicates a specific speed bin and package configuration within the broader product line.

Memory IC Replacement Considerations

IDT71V3558XS133PF8 is available in tape-and-reel packaging as an alternative form factor.
